BMW 520i vs Toyota BZ4X

What's the difference?

There’s no getting around the i5 being a rather expensive offering. More than $150,000 to get into an electric sedan that’s not much faster than a hot hatch is a big ask, but there’s plenty to enjoy about the 5 Series.

Things like its heated leather seats shouldn’t be the reason you’re willing to spend so much on a sedan when a $50,000 hybrid SUV will score you the same, instead it’s the fact the 5 Series is a delight to drive and hasn’t lost the feeling of prestige the badge has earned over the last half a century.

In terms of value - if speed isn’t your focus and you’re less of a gadget-type-operator when looking at cars like this - the 520i has the style and comfort you’d need and at $100K less than the M60.

And in terms of large electric sedans, the i5 eDrive40 is cheaper than a Porsche Taycan (by a little) or an Audi e-Tron (by a lot). The Genesis G80 Electrified is the closest cheaper rival, by about $10K, or the less powerful Mercedes EQE is similarly priced at $154,900.

Essentially, if you’re looking at a 5 Series, it might be worth considering if you really need it to be electric, but if so, there aren’t many alternatives in its category for the price.

When the bZ4X first launched it was already late to the game and blended into the background too much. However, this update has dramatically improved its appeal.

Despite this, the electric mid-size SUV segment is incredibly fierce and it’s hard to not get caught up in glitzier rivals like the BYD Sealion 7, Tesla Model Y and Zeekr 7X.

It’ll be interesting to see whether the Australian public reacts to this update and if it draws in more punters.

If you’ve watched other members of the BMW family go into a new generation within the last few years - the 3, 4 and 7 Series particularly, you won’t be too surprised by what you see here. Especially with the latter, having seen the petrol variants look roughly the same as the electric ones.

BMW specifically made the petrol 520i and the i5 variants look similar for egalitarian purposes - to not disenfranchise 520i buyers who are still spending a fair chunk of cash but might not be ready to go EV.

That means all three variants score a mix of new and old. The kidney grille remains and isn’t as large as on the M3 or 4 Series, while the bonnet line following it and the ‘character line’ down the car’s side also remain. And yes, the Hoffmeister kink where the C-pillar meets the passenger window’s lower corner is still there.

On that C-pillar though is a ‘5’ stamped into the bodywork, new to this generation, while the front grille as mentioned has a glowing light surround - the brand’s ‘Iconic Glow’ already seen on the 7 Series.

Overall, thanks to being slightly larger in every dimension, the new 5 is starting to look bigger than a 7 Series from a little while ago. And that’s because it is - its body is overall longer than an E65 7 Series from the mid-2000s.

It’s 5060mm long 1900mm wide, 1515mm tall (97mm longer, 32mm wider, and 36mm taller). Its wheelbase is 20mm longer too at 2995mm. 

The exterior design of the bZ4X never really blew me away. It’s just sensible and not too out there. In saying that though, being sensible is no bad thing and can be seen as a positive for some buyers.

This facelift has brought Toyota’s new corporate look, including the hammerhead shark-like LED lighting signature. It already features on models like the C-HR, Camry and RAV4. In fact this update has made the bZ4X look more like an electric RAV4 than ever before.

I like the C-shaped daytime running lights but I’m not a fan of how the main headlight section is now separate. I prefer how they looked before.

The black wheel arch cladding is now also glossy and not matte. Sure, this looks great right now, but it likely won’t be long until it unfortunately gets scratched.

Inside, if you covered up the Toyota badge you could likely fool me into thinking this is a Lexus. The new 14.0-inch touchscreen is virtually identical to the one in models like the Lexus NX, RX and GX.

There are also plenty of premium-feeling soft-touch materials around the cabin. I’m not a huge fan of the grey and white two-tone interior, at least from a family-friendly standpoint, but thankfully you can get an all-black interior instead.

Another major design change with the interior is the new centre console. It now features two wireless chargers and a revised button layout. I particularly like it because it’s no longer covered in glossy piano black.

A longer wheelbase means more space inside, where the 5 Series also still looks fairly familiar to those who have spent any significant time in a recent model BMW.

BMW has historically been pretty bang-on with ergonomics, and the new-gen 5 does a good job of sticking to that. Comfortable sports seats and quality feel for the materials on touch points mean the 5 Series feels nice to be in, and relatively restrained interior design for a somewhat luxurious car means it looks nice too.

It’s let down only by a couple of things - its multimedia screen and Operating System 8.5 is a little less simple to use now, and requires more touching the screen than previous iDrive systems, rendering the scroll wheel less useful.

The BMW Interaction Bar too is a little tricky to see controls on, as well as lacking physical feedback for using controls. Vent flow controls are digital sliders on the Bar, while vent direction is controlled by an unusual ‘joystick’ style control nearby.

The rear seat is plenty spacious, as you’d expect from a large sedan, with climate controls and ports for charging devices in the rear.

The front seats in the bZ4X are deliciously comfortable and supportive. They make long trips a breeze, plus the ventilation that’s standard on the AWD trim works well in the heat.

Despite this, I’m still not a huge fan of the driving position. You need to look over the steering wheel in order to view the almost windscreen-mounted digital instrument cluster. It’s a similar set-up to what Peugeot employs and is intended to reduce the amount you need to stray your eyes from the road.

I appreciate this but it just doesn’t work for everyone. Personally I need to jack the seat up more than I’d like in order to see the screen fully. When I do this my knees get in the way of the steering wheel no matter how I position it, which isn’t ideal.

The set-up in the related Solterra is a little better as it has a squared-off steering wheel instead of a traditional round steering wheel.

Going back to the digital instrument cluster, the content display on this is still rather limited. Thankfully, critical information like your current speed is displayed clearly, but having added customisation through more informative displays to toggle through or more themes would be a nice extra touch.

Moving across the larger touchscreen multimedia system is a welcome addition, but I didn’t think there was anything wrong with the old one. The user interface is still basic in a good way, meaning it’s hard to get lost.

A difference is the climate control features are now fully integrated into the touchscreen, save two physical dials that change the dual-zone climate control temperature.

While this means you need to press on the touchscreen to change certain climate control-related features now, a lot of these in the pre-update were touch-sensitive buttons on a panel under the touchscreen. Really, it makes no difference.

Wireless Apple CarPlay and Android Auto are still standard and work flawlessly with my iPhone 15 Pro Max. There are now also two wireless chargers, which is great if you want to charge your phone and your passenger’s phone.

However, they don’t work properly as they don’t offer any ventilation. They regularly make my phone overheat and stop charging, even on shorter trips. If you want to reliably top your phone’s battery up, it’s best to just plug into a USB port with a cable.

Looking elsewhere around the cabin, there is an adequate amount of storage, though some more would be nice. There are two decently sized cupholders, a small shelf under the centre console and a side-hinging centre console box. Like the pre-update version, there is still no proper glove box.

In the second row there’s plenty of legroom available for adults behind adults, though due to the placement of the high-voltage battery this leaves you with a knees-up feeling. This is common in a number of EVs, even some that are based on dedicated electric architectures, like the bZ4X.

Headroom also isn’t fantastic as the roof starts to taper back where your head is located. You wouldn’t want to be much taller than 180-odd centimetres back there. It’s also made worse when you recline the seat backrest.

Second-row amenities include air vents, heated outboard rear seats, USB-C ports, seatback map pockets, as well as a fold-down armrest with some cupholders and a tablet holder.

At the back there is a hands-free power tailgate which is rather slow to open and close and makes plenty of beeping while doing so. It's a classic Toyota on this front.

The bZ4X AWD offers 410L of boot space with the rear seats upright which is slightly less than the 2WD due to the added rear electric motor.

It’s a decent space but doesn’t stand out from the crowd. There’s some extra underfloor storage which is large enough to fit some cables and that’s about it. Unfortunately there’s no front boot.

Boot-related amenities include a cargo blind, a variety of hooks, as well as vehicle-to-load (V2L) capability using 220V/1500W AC inverter and a single household power socket. The latter allows you to power household appliances using the vehicle’s high-voltage battery.

Disappointingly there is no spare wheel, but this isn’t uncommon for EVs. You have to make do with a tyre repair kit, which is fine if you have a small air leak but pointless if you have a proper puncture.

There are still only two trim levels in the bZ4X line-up – 2WD and AWD, the latter on test here.

Compared to the pre-update version, pricing has been slashed by up to $10,000, depending on the variant.

The line-up now starts at $55,990, before on-road costs, for the 2WD and extends to $67,990, before on-road costs, for the AWD.

This top-spec bZ4X AWD now undercuts the corresponding Subaru Solterra AWD Touring by $2000. These two cars are twins under the skin and are built in the same Japanese facility.

It also undercuts the top-selling Tesla Model Y Long Range AWD by $1000, which is a major feat. However, certain rivals like the BYD Sealion 7 Performance and Zeekr 7X Long Range are still cheaper but not all of them offer all-wheel drive.

With this update there’s now a larger 14.0-inch multimedia touchscreen, two wireless phone chargers, vehicle-to-load (V2L) capability, plus a hands-free power tailgate and heated steering wheel standard across the line-up.

This is above and beyond the standard LED headlights, roof rails, dual-zone climate control and heated front seats with electric adjustment in the 2WD.

The AWD brings larger 20-inch alloy wheels, a panoramic glass sunroof, a nine-speaker JBL sound system, digital rear-view mirror and ventilated front seats.

This is a lot of standard equipment and you can’t really complain because you’re getting all of this for less than before.

Despite BMW calling it ‘electrified’, the base 520i is only a mild hybrid so most wouldn’t realise unless they were told.

Its turbocharged 2.0-litre four cylinder puts out a modest 153kW and 330Nm, with power and torque sent to the rear wheels via an eight-speed automatic transmission.

BMW claims it’ll knock over the 0-100km/h sprint in 7.5 seconds, a few seconds too slow to blow anyone’s socks off.

The mid-spec eDrive40 has a little more kick to it, its rear-mounted electric motor capable of 250kW/430Nm and able to cut that time to 6.0 seconds.

It’s fitted with an 84kWh battery to draw its power from, the same as the 442kW/820Nm M60 with its all-wheel drive dual-motor setup.

The M-tuned i5 can hit 100km/h in a claimed 3.8 seconds. Bye bye socks, perhaps.

While there have been a number of spec changes or additions with this update, even more tweaks have happened under the skin.

All versions of the bZ4X now make more power and torque. The AWD’s dual electric motor set-up now has a total system output of 252kW (+92kW) and 438Nm (+101Nm).

Like the pre-update version, the bZ4X AWD offers 'X-Mode' off-road drive modes, crawl control, as well as downhill assist control. However with 20-inch alloy wheels as standard, I doubt these will be taken off the beaten track very often, if at all.

BMW claims the petrol 520i sips 6.7 litres per 100km from its 60-litre fuel tank, though we were unable to independently test any of the claimed figures on the launch day.

The base car has a theoretical range of 896km if it was possible to achieve the claimed fuel consumption figure for the duration of the whole tank - but it isn’t and realistically you could knock about 20-30 per cent off that, depending on how enthusiastically you drive.

In the i5 variants, the same 84kWh battery provides slightly different ranges due to the eDrive40 using 16.56kWh per 100km, and the M60 using 18kWh.

The eDrive40 has a claimed 550km maximum range, while the M60 has a 506km figure thanks to its extra motor and weight.

Another big under-the-skin change with this update is Toyota has fitted the bZ4X line-up with a larger 74.7kWh lithium-ion battery pack.

As a result this EV has more range. The AWD now offers up to 517km of WLTP claimed range (up from 411km) with an official energy consumption figure of 16.0kWh/100km.

During my largely urban testing over the Christmas break I saw an average energy consumption of 14.4kWh/100km. In fact, on one particular trip into the city with minimal traffic I saw an average energy consumption of 10.5kWh/100km. This is incredibly low for an all-wheel drive EV and almost Tesla-like.

Using my as-tested energy consumption figure, the bZ4X AWD has a theoretical total range of 518km.

The Type 2/CCS combination charge port remains on the left-hand front wheel arch which is fine because it’s kerbside, but at some public charging stations it can be hard to connect the cable without having it run up against the front bumper.

Speaking of charging, the maximum AC charging rate has now been upped all the way from 11kW to 22kW, which is a fantastic update. This now allows for a 10 to 100 per cent charge in 3.5 hours.

While peak DC fast-charging unfortunately is still capped at 150kW, Toyota claims it can remain at a higher charge rate for longer now thanks to reworked battery thermal technology.

A fast charge from 10 to 80 per cent is now meant to take 45 minutes. It would be good to see quicker charging because many of this car’s rivals are faster and this can make a world of a difference during long road trips.

For some cars, the list of features is what really separates the variants, but that’s not the case for the 5 Series. As is a bit of a BMW tradition, the drivetrains dictate the different trim levels and prices, and there are three fairly distinct flavours of 5 Series.

Starting at ground level, the 520i might at first seem like a bit of boring vanilla. Except it’s actually quite smooth and light vanilla.

There’s not a lot to write about when it comes to its drivetrain, but the lightness of its engine and petrol tank combo when compared to EV batteries and motors is refreshing, and makes for a quite dynamic rear-drive sedan.

Its 153kW and 330Nm is delivered smoothly enough with the mild hybrid assistance doing a little in helping responsiveness, but without intervening in the gearshifts it doesn’t feel particularly keen.

It lacks the ride comfort of the i5’s adaptive suspension, but it’s able to be driven in a spirited manner that belies its size and even, to some extent its 1725kg kerb weight. Chocolate sprinkles on the vanilla, if you like.

It’s not fast, but it feels nimble compared to its electric siblings and can carry a fair bit more speed through corners, after which there’s room to notice its rear-drive characteristics.

It’s especially noticeable after getting out of the 2130kg eDrive40, though the extra power from its 250kW/430Nm motor makes for some more spirited acceleration and a little more excitement when exiting a corner, especially if you’re aiming to double-check if it really is rear-wheel drive. There’s a little more than choc-topped vanilla going on here.

The steering is, like in the 520i, direct and responsive, though in most cases is probably best set to ‘comfort’ rather than ‘sport’ in its settings. 

The eDrive40 is rather comfortable and capable when barrelling through twisty backroads, and doesn’t feel out of hand for a five-metre-long sedan. It holds its weight well, and telegraphs when you might be approaching the limit quite sensibly.

When considering that, then, it’s impressive how brutally capable the 2305kg M60 is.

Here, we’re looking at a double-choc fudge with extra choc, and maybe some cookie dough in there for good measure. There’s a lot to like, but boy is it heavy.

It’s 580kg (or exactly half a Peugeot 208 GTi) heavier than the 520i, but it feels quick on its feet and its anti-roll seems to do a lot in terms of dynamics, the limiting factor really seems to be its tyres (which can and will squeal quite quickly to let you know when approaching said limit).

While you’ll need to take caution with how much speed you approach a corner with, you’re not going to lack acceleration on the other side, its all-wheel drive being less ‘fun’ but more efficient at getting you away from the bend than in the rear-drive eDrive40.

That adaptive suspension does also translate to a comfortable ride on relatively rough roads - only particularly bad bumps will reveal how much weight and pressure is being placed on each corner of the big sedan.

The bZ4X AWD was never a slow car to begin with but the added oomph is welcome.

While it's not overtly noticeable in everyday driving, when you mash the throttle at the lights you're pinned back in the seat a lot more than before.

Despite this, it still doesn’t feel like this car wants to be driven quickly. If you drive with a docile right foot, the bZ4X is a supremely comfortable vehicle that’s relaxing and easy to drive.

There are a number of regenerative braking modes to select from by using the steering wheel-mounted paddle shifters, but none of them offer a one-pedal driving mode. This means you need to use the brake pedal to come to a complete stop.

As a result, this car’s driving experience is more like a combustion or hybrid vehicle, like the RAV4. This can make the transition to an EV easier if you’ve never driven one before.

The steering feel in the bZ4X has a noticeable weight and heft to it which feels nice when you’re zipping around on urban streets. It also feels like the steering wheel is actually connected to the wheels rather than the overly assisted and light steering systems in some of its rivals.

Where the added steering heft can feel a touch annoying is when you’re doing a tight parking manoeuvre. This car is longer than you think, meaning you may need to do three-point turns more often.

Speaking of parking, the bZ4X’s surround-view camera system is detailed and high-resolution, which is a great peace of mind. The semi-autonomous park assist is also fantastic as it can detect and park the vehicle within painted lines, rather than just slot it between two parked vehicles.

Adding to the comfort factor is this car’s ride, which is a major highlight. Despite the large 20-inch alloy wheels, the suspension does a great job at softening bigger bumps and small road imperfections.

There is little that upsets the interior ambience in this car, making it a serene place to be regardless of where you’re travelling. For an EV you’d expect more tyre and wind noise given there’s no engine to drown the noise out, but Toyota has seemingly done a great job of insulating the cabin and choosing suitable tyres.

The updated bZ4X still has a maximum five-star ANCAP safety rating based on testing conducted on the pre-update car by Euro NCAP.

Toyota has notably now made the full safety suite standard across the entire line-up. 

Previously the 2WD missed out on features like blind-spot monitoring and a surround-view camera, among others.

As standard there are eight airbags, autonomous emergency braking (AEB), rear cross-traffic alert, lane-keep assist, adaptive cruise control, driver attention monitoring and traffic sign recognition.

There’s also connected services with SOS emergency calling, plus automatic collision notification, vehicle insights and charge station search available with a smartphone companion app.

All of the safety systems operate in a seamless manner and don’t interrupt the driving experience unless they actually need to. This is becoming increasingly uncommon.

BMW has a fairly industry-standard five-year/unlimited kilometre warranty on its new cars, while its electric car batteries are covered by an eight year/160,000km warranty.

For servicing, BMW offers numerous discounted packs and deals based on your preferences and desire to pay upfront.

For the 5 Series, a five-year/80,000km basic service package is $2400, though the i5 will have different needs and lower servicing costs not yet listed by the brand.

As standard there is a five-year, unlimited-kilometre warranty which is fine but does not stand out for the segment anymore.

However, if you service at one of Toyota’s 260+ dealers around Australia when required, warranty coverage for the high-voltage battery can be extended all the way out to 10 years.

Logbook servicing is required every 12 months or 15,000km, whichever comes first, and the first five services are capped at $180 each. While the pricing in classic Toyota fashion is competitive, the 12 month intervals aren’t (in the EV space). The standard is now closer to 24 months.

As part of the ownership package owners get Mode 2 and Mode 3 charging cables. The 'Toyota Go' loyalty programs also allows for the choice of a complimentary 7.0kW home charger or 12-month Chargefox subscription.
